图1示出应用了本发明的数字复制机的图像处理方框图的一个例子。 FIG. 1 shows a block diagram of an example of an image processing digital copying machine according to the present invention.

在扫描仪单元100,利用光学方法读取文档,然后,对获得的图像信号进行模数变换,以产生数字图像信号。 In the scanner unit 100, reads a document by an optical method, and then the image signal obtained by analog-digital conversion to produce a digital image signal. 在图像处理单元101,对产生的图像数据进行适当处理,在打印机单元102,利用墨粉或墨水,在纸张上形成图像,从而完成复制。 In the image processing unit 101, the image data generated by appropriately processing 102, using toner or ink to form an image on a sheet in the printer unit, thereby completing copying.

在图像处理单元101上,首先,在处理器105的控制下,使输入的图像数据容纳在页式内存103中。 In the image processing unit 101, firstly, under control of processor 105, the input image data received in the page memory 103 in the formula. 页式内存103由例如SDRAM等以及用于控制SDRAM的ASIC和图像压缩/放大ASIC等构成,它具有可以存储整个文档的图像数据的容量。 Memory page 103 is composed of, for example, an SDRAM and ASIC for controlling the SDRAM and the image compression / expansion ASIC, etc., which can have a capacity to store the entire document image data. 在需要时,将容纳的图像数据发送到存储器(硬盘等),利用处理器105,对应于控制板106上的操作结果,对该图像数据进行可变比例系数处理和配置处理(下面做说明)。 When needed, the received image data is transmitted to the memory (hard disk), with a processor 105, corresponding to the result of the operation on the control panel 106, a variable scale coefficient processing and configuration process (described below do) the image data . 再通过存储器104和页式内存103,将已经被处理的图像数据输入到图像分割单元107和过滤器单元108。 Through the memory 104 and page memory 103, the image data has been input to the image segmentation processing unit 107 and the filter unit 108.

在图像分割单元107,利用诸如索贝尔(Sobel)过滤器的边缘检测过滤器,进行提取输入图像中部分字符或线图的处理,然后,根据该结果,在过滤器单元108执行切换字符加重过滤器和平滑过滤器等处理过程。 In the image segmentation unit 107, using an edge detection filter such as a Sobel (the Sobel) filter, the input image processing section extracts character or line drawing, then, according to the result, switching character emphasis filter unit 108 filters It is peaceful glide filters, and other processes. 将已经进行了过滤处理的图像数据输入到色调处理单元109,然后,根据打印机单元102的特性进行伽马校正处理、屏幕处理等。 The filtering process has been performed is input to the tone of the image data processing unit 109, and then performs gamma correction processing, screen processing unit 102 according to characteristics of the printer.

图2示出根据本发明第一实施例的处理器105的处理过程的流程图。 Figure 2 illustrates a flowchart of a processing procedure of the first embodiment of the present invention, the processor 105. 在本实施例中,利用其中缩小多个文档图像并将它们合成为一个文档图像的处理为例,说明本发明。 In the present embodiment, wherein the reduction using a plurality of document images and synthesizes them into a document image processing as an example, the present invention is described.

首先,在步骤S200,根据累积在存储器104内的图像数据,对每个文档图像进行布局分析以便用于后述配置处理过程。 First, at step S200, the accumulated in the memory 104 in accordance with the image data, for each document image for layout analysis processing configuration to be described later. 具体地说,对于每个文档图像,提取一个或者多个分别含有图像对象的矩形区域(换句话说,对文档图像进行分割),然后,确定每个矩形区域的各顶点(扫描的起点和终点)的坐标。 Specifically, for each document image, or extracting a plurality of rectangular regions each containing an image object (in other words, the document image segmentation), then, to determine the vertices of each rectangular region (scanning start and end points )coordinate of. 图3是布局分析处理过程的处理结果的一个例子。 Figure 3 is an example of the layout analysis processing result of the processing procedure. 在文档图像D1上,提取包括图像对象的矩形区域(以下简称矩形区域)L1,然后,确定起点(X1,Y1)和终点(X2,Y2)。 The image on the document D1, extracts a rectangular region including an object image (hereinafter referred to as the rectangular region) Ll, then, determines the starting point (X1, Y1) and end point (X2, Y2). 在文档图像D2上,提取矩形区域L2和L3,然后,确定矩形区域L2的起点(X3、Y3)和终点(X4、Y4)以及矩形区域L3的起点(X5,Y5)和终点(X6,Y6)。 On the document image D2, extracted rectangular regions L2 and L3, and then, determines L2 starting rectangular area (X3, Y3) and end point (X4, Y4), and L3 is the starting point of the rectangular area (X5, Y5) and end point (X6, Y6 ). 请注意,区域L1和L2是包括字符对象的文本区域,而区域L3是包括图片对象的图片区域。 Note that the region L1 and L2 are the text objects including a character region, and L3 is a region including the picture object image area. 此外,作为另一个实施例,仅显示缩小的文档图像,而且利用控制板106,根据该显示,用户可以人工执行这样的提取矩形区域操作。 Further, as another embodiment, only the display of the document image is reduced, and the use of the control panel 106, according to the display, the user can manually perform such rectangular area extraction operation.

在步骤S201,参考在步骤S200确定的各矩形区域的顶点坐标信息,执行诸如“二合一”或“四合一”的处理,其中将多个文档图像配置到一个输出图像的各区域中。 In step S201, the vertex coordinate information of each of the reference rectangular area determined in step S200, performs processing such as "combo" or "four", wherein a plurality of document images arranged into a region of the respective output image. 二合一意味着其中将两个文档图像配置(合成)到一个输出图像中的处理过程,而四合一意味着其中将4个文档图像配置到一个输出图像中的处理过程。 Means combo configuration wherein two document images (synthesis) process to an output image, and wherein means Four four document images arranged into a process in the output image. 然而,在该阶段,仅定位各矩形区域,而不实际配置图像数据。 However, at this stage, only the positioning of each rectangular region, and not the actual configuration of the image data.

在步骤S202,如图4所示,在控制板等上显示步骤S201的分配处理结果。 In step S202, shown in Figure 4, show the distribution of the processing result of step S201 on the control board and the like. 接收用户基于该显示发出的指令,每次在接收指令时,进行再配置和再显示。 Receiving a user instruction issued based on this display, each time receiving an instruction, re-configuration and re-display. 在图4所示的显示屏幕110上,提供用于显示图像布局的布局显示区和用于显示各操作键等的单独操作区。 On the display screen 110 shown in FIG. 4, a layout for displaying a layout image display area and the area for displaying the individual operating the respective operation keys and the like.

图4示出其中缩小两个A4尺寸的文档并将它们配置到一个A4尺寸的文档中各区域的例子。 Figure 4 shows a reduction which two A4-size document, and an example of a A4 size document are arranged to each region. 换句话说,缩小两个A4尺寸的文档并将它们合成为一个A4尺寸的文档。 In other words, reduce the two A4-size document and synthesizes them into a document of A4 size. 因此,整个文档图像的要求放大系数是71%。 Therefore, the entire required document image magnification factor is 71%. 请注意,利用包括如图4所示显示单元的控制板,可以任意设置要配置的全部多个文档图像的放大系数。 Note that, by using a display unit comprising a control panel shown in Figure 4, you can be arbitrarily set the amplification factor of all the plurality of document images to be configured. 此外,可以将要这样配置的多个文档图像的放大系数设置为互相不同的值。 Further, the amplification factor of the plurality of document images can be so configured to mutually different values. 此外,作为另一个实施例,只要仅单独设置要配置的各文档图像的比例系数就够了,而不提取矩形区域或者分割该区域。 Further, as another embodiment, as long as each document is provided only a single image of the proportional coefficient to be configured is enough, without extracting the divided rectangular area or region.

在单独操作区上,提供当前活动的区域的区域名、比例系数指定键以及位置设置键。 In a separate operation area, the currently active region of the zone name, the location and the scale factor setting key specified key. 利用位置设置键,用户可以选择显示在布局显示区上的矩形之一。 Using a position setting key, the user can select one of the displayed rectangle on the layout display area. 例如,利用粗闭合线,使选择的矩形区域显示为活动区域,而且将其区域名显示为活动区域名。 For example, using a thick line is closed, the selection area is displayed in a rectangular active area, and an area name which is displayed as an active region domain. 利用比例系数指定键,用户可以指定活动区域的比例系数。 Using the scaling factor designation key, the user can specify the scale factor of the active area. 按照所指定的比例系数,显示在布局显示区上的活动区域的尺寸发生变化。 Scale factor designated, the display area size of the active display region on the layout is changed. 每次改变指定的比例系数时,改变活动区域的尺寸。 When each specified scale factor changes, changing the size of the active area.

在此,为了能进行这种操作,需要这样进行设置,使得对应于改变后的布局内的矩形区域完全覆盖缺省布局内的矩形区域。 Here, in order to carry out this operation, it is necessary to set so that a rectangular area within the layout corresponding to the changed completely cover a rectangular area within the default layout. 具体地说,目标矩形区域的比例系数必需大于或者等于整个文档的比例系数。 Specifically, the target scale factor necessary for the rectangular area scale factor of greater than or equal to the entire document. 例如,在整个文档的放大系数是71%时,目标矩形区域的放大系数必需大于或者等于71%。 For example, the amplification factor is 71% of the whole document, the amplification factor of the rectangular target area must be greater than or equal to 71%.

在文档图像和按比例发生变化的矩形区域重叠的区域上,只有矩形区域的图像数据可用。 And the document image on a rectangular region ratio changes overlap, only the image data of the rectangular area is available. 将重叠区域的宽度设置得与矩形区域的外围一致。 The width of the overlapping regions is set to be a rectangular region coincides with the peripheral. 然而,通过利用控制板改变矩形区域的位置,还可以将重叠区域的宽度设置得在该矩形区域左、右或者上、下不对称。 However, changing the position of the control board by using a rectangular region, the width of the overlapping area may also be set in the left, right or on the rectangular area, asymmetric.

在用户按下执行按钮(未示出)时,在步骤S203执行可变比例系数处理。 When the user presses the execute button (not shown), in step S203, the processing execution variable scale factor. 具体地说,根据如图4所示布局显示区上显示的布局,对各文档图像全体进行可变比例系数处理,配置按比例变化的文档图像数据,对每个矩形区域进行可变比例系数处理,以及对按比例变化的文档图像配置矩形区域数据。 More specifically, as shown in FIG. 4 in accordance with a layout display layout on the display area, the document image for each variable scale factor for the entire process by the document image data arranged in varying proportions, for each rectangular area variable scale coefficient processing and varying proportions according to the document image data arranged rectangular region pair. 总之,合成按比例变化的文档图像和按比例变化的矩形区域。 In summary, the proportional change synthetic document image and proportional change in the rectangular area. 这样,将多个文档图像合成为一个文档图像。 Thus, a plurality of document images into a document image.

请注意,在上面的说明中,说明了将本发明应用于缩小文档图像的情况的例子。 Note that in the above description, an example of the present invention is applied to the reduced document image. 然而,本发明并不局限于缩小情况,而且还可以应用于等比例(倍数=1)的情况。 However, the present invention is not limited to the case of reduction, but also may be applied to other case where the ratio (ratio = 1). 在这种情况下,将提取的矩形区域的比例系数设置为大于或者等于1的值。 In this case, the scale factor of the extracted rectangular area is set to a value greater than or equal to 1. 因此,在复制时,仅对文档中其字符太小以致不能读的文本进行放大。 Thus, when copying, the document which only characters too small to read the text enlarged.

接着,将说明与对矩形区域进行可变比例系数处理有关的另一个不仅以区域尺寸按比例一致变化的方式,而且以如图5所示可按比例仅改变已经提取的字符串与字符串之间的间隔的方式,对文本区域进行可变比例系数处理。 Next, will be explained with variable scaling factor treatment rectangular area to another area is not only related to the size scale consistent changes, and 5 may be scaled to change the string of the string have been extracted and shown only between spaced manner, the text area variable scale coefficient processing. 具体地说,如果仅图5中的阴影区域所示的非字符串区域(坐标为y2-y1,y4-y3,...)的纵向是进行可变比例系数处理的对象,则通过利用下面的公式(1),将文档比例系数Rorg变换为实际比例系数R:R={Ymax×Rorg-∑(y(2n+1)-y(2n))}/{Ymax-∑(y(2n+1)-y(2n))}...(1)可以进行可变比例系数处理,其中Ymax是文本区域r可变比例系数处理对象方向的尺寸,n是大于或者等于0的整数,y(2n)和y(2n+1)分别表示字符串区域的起点和终点。 Specifically, if a non-vertical hatched region character string region shown only in FIG. 5 (coordinates y2-y1, y4-y3, ...) of the object is a variable scale factor processed, by using the following equation (1), the document is converted into an actual scale factor Rorg proportional coefficient R: R = {Ymax × Rorg-Σ (y (2n + 1) -y (2n))} / {Ymax-Σ (y (2n + 1) -y (2n))} ... (1) variable scale factor can be treated, where Ymax is the size of the direction coefficient processed text area ratio variable r, n being an integer greater than or equal to 0, y ( 2n) and y (2n + 1) respectively represent the start and end character string region.

在此,各种方法可以用作提取字符串的方法,例如,可以提供一种包括步骤200的布局分析处理的方法,下面对它进行说明。 Here, various methods can be used as a method for extracting a character string, for example, a method may be provided in the layout analysis processing step 200 comprises, it will be described below.

图6是示出用于说明根据本实施例,处理器105执行的布局分析处理过程的流程图的一个例子。 FIG 6 is a diagram for explaining an embodiment according to the present embodiment, the layout analysis processor 105 performs a processing procedure example of a flowchart.

首先,在步骤S600,根据密度,三元化输入图像的各像素,并将它们分类为背景区域、字符区域和半色调区域。 First, at step S600, the based on the density of each pixel of the input image triplicating, and they are classified as the background region, character region and the halftone region. 在步骤601,在字符区域上,尺寸大于或者等于预定区域的区域被重新分类为半色调区域。 In step 601, in the character region, the size is greater than or equal to a predetermined area is reclassified as a halftone region. 在步骤S602,利用矩形包围字符区域上的剩余像素,使其用作文本区域,因此,字符区域上的相邻像素之间的距离是预定值或者更小。 In step S602, the remaining pixels surrounded by a square on a character region, so that as the text area, and therefore, the distance between adjacent pixels in the character region is the predetermined value or less. 同样,利用矩形包围半色调区域,而且使它用作图片区域。 Similarly, the use of a rectangular region surrounding the half-tone, and it is used as image area. 请注意,例如在第11-69150号日本专利申请公报中公开了布局分析处理过程的细节,其中识别各区域。 Note, for example, discloses details of the layout analysis processing in the first Japanese Patent Application Publication No. 11-69150, in which each region identified.

在步骤S603,在文本区域上,如图7所示,分别在横向和纵向投影字符区域的像素,然后,产生直方图(像素频率分布)。 In step S603, in the text area, as shown in Figure 7, each pixel in the horizontal and vertical projection of the character region, and generates a histogram (frequency distribution of the pixel). 对于直方图中的最大值与最小值之间的差值大而且最大点之间的间隔宽的方向(该图中的纵向),通过二值化频率,检测字符串。 For a large difference between the histogram and the maximum and minimum spacing width direction (vertical direction in the figure) between the maximum point, binarization by the frequency detection strings. 在步骤S604,将各矩形区域(文本区域、图片区域等)的扫描方向上的起点和终点的坐标,以及对于文本区域在该区域内的字符串方向上的检测的字符串区域的起点和终点作为数据附加到图像数据上。 S604, the start and end points, the coordinates of the start and end points of the respective rectangular area (text area, image area, etc.) in the scanning direction, and the region character string for a text string in the region of the detection region of the direction of the step of as data is added to the image data. 这样,进行包括字符串提取过程的布局分析。 Thus, the layout analysis includes the character string extraction process.

如上所述,根据本发明,在按比例改变文档并复制文档时,通过以不同于整个文档的比例系数的比例系数改变文本区域的比例系数,可以防止读取文本困难。 As described above, according to the present invention, when changing the proportion document and copy the document, by the scale factor scaling factor different from the scale factor changing the entire document text area can be prevented difficult to read the text.

上面描述了本发明实施例,而且本发明的设备和方法并不局限于此,可以实现各种修改的例子。 The above described embodiments of the invention, and methods and apparatus of the present invention are not limited thereto, examples of various modifications may be implemented. 这种修改的例子包括在本发明中。 Examples of such modifications are included in the present invention. 此外,通过适当组合各实施例中的各部件、功能、特征或方法步骤而配置的设备或方法包括在本发明中。 Further apparatus or method, by properly combining the components of the embodiments, functions, features or method steps configured in various embodiments of the present invention comprises.

例如,在上面的说明中,说明了一个例子,在该例子中,本发明应用于多个文档图像的缩小和合成处理,例如二合一处理。 For example, in the above description, an example described in this example, the present invention is applied to a plurality of reduction and synthesis processing a document image, e.g. combo treatment. 然而,显然,本发明可以应用于对单个文档图像进行缩小处理过程、等比例处理过程或放大处理过程。 Obviously, however, the present invention can be applied to image reduction processing of a single document, proportional amplification process or processes. 此外,在上面的说明中,描述了将文本区域的比例系数设置为与其它区域的值不同的值。 Further, in the above description, the scale factor described in the text area is set to a value different from the value of the other areas. 然而,不用说,可以将图片区域的比例系数设置为与其它区域的值不同的值。 However, needless to say, the scale factor of the image area can be set to a value other areas of different values.
